…I did glean plenty of information to be able to tweak / adjust the way that I have come to dye fabric over the years.  I must admit that initially I was skeptical and a bit arrogant – I knew what I was doing.  After all, I’ve been dyeing fabric for almost 20 years.  Now I most humbly admit that I was wrong.  Your system of (edit: a technique in the class) blew me away.  It made me realize that I’ve wasted a lot of dye over the years, in the sense that I was using too much dye powder initially.  Also, it was like a moment of epiphany when I realized all the possibilities for being able to measure exact amounts of dye stock to create a myriad of colors.  I can never thank you enough.
